Description

Pyrocoustic Sealant is an acrylic based sealant used to reinstate the fire resistance performance of wall and floor constructions where they have been provided with apertures for the penetrations of multiple services, also to form linear gap seals where gaps are present within the wall and floor constructions and linear joints where wall and floor constructions abutt. Pyrocoustic Sealant has slight intumescent properties that cause it to swell upon heating.
